Official fuel tank size? (USA)
Hi all,
I currently own a 2019 CLS450 and am considering a new E450. One of the things I love about the CLS is its massive fuel tank, which is 21.1 gallons. I thought the new E-Class would have the same fuel tank size as the CLS and previous generation W213 E-Class, however there's conflicting information on the actual tank size. The EPA claims that it's still 21.1 gallons for the 2024 E450, however on the Mercedes Benz USA official site, they list the tank size as being 17.4 gallons. Can one of you kind gentleman verify which one is the correct number? It would be a shame if the fuel size has indeed been drastically reduced to such an extent.

It would be shame if for MY 2025 the E450 went to the smaller tank - but I doubt anything can be done - just as the luxury version of the MY 2025 is not available in the US - but almost everywhere else.

Thank you for confirming, everyone. Very strange and unfortunate decision on MB's part when the fuel economy appears to be the same between the prior and current generation.

One of the most annoying things about my 2022 is that the ‘miles to empty’ stops displaying when you get to the reserve…just when you need it most.
I wonder if any of this is related to the fuel pump recall the W213 had.

Perhaps both are correct? My 2022 E450 AT owners manual states 21.1 gallons of which 3.2 gallons is reserve. Maybe the MB site is not including the ‘reserve’ portion?

Since the 17.4 gallons is labelled as the "total fuel tank capacity" I would think that that number already includes the reserve amount. Meaning that we have only 15.6 gallons until it's labelled as "empty" on the gauges before going into reserve.
On the bright side, this is still a larger fuel tank than the new BMW 5 Series which maxes out at 15.9 gallons, though it does get slightly better fuel economy.
